Re: 4 month visit
There's no such thing as low fat human milk. And when it comes to weight gain, what matters is not the "type" of milk baby gets (i.e. low fat vs. high fat) but rather how much milk a baby takes in. A baby can grow and thrive on the lower-in-fat "foremilk" alone, provided he or she gets enough of it. And a baby who is being nursed on demand and is wetting/pooping normally- that's a baby who is getting plenty of milk!
If your other 2 kids are small and lean, and you and your husband have small/lean builds, it certainly points to there being a genetic explanation for your child's size.
How many times per day does baby nurse?
